Hello first of i am new to Golang and am trying to upload a photo to my s3 Bucket however I am getting an error every time I try, the error I get is this
err opening file: open 55fc14631c00004800082775.jpeg: no such file or directory2016/11/30 19:28:10 http: panic serving [::1]:58502: runtime error: invalid memory address or nil pointer dereference goroutine 5 [running]
My buckets permission are set to read and write for everyone so it must be something in this code is that wrong
and I am following this tutorial https://medium.com/@questhenkart/s3-image-uploads-via-aws-sdk-with-golang-63422857c548#.ahda1pgly and I am trying to upload a public image found here http://img.huffingtonpost.com/asset/,scalefit_950_800_noupscale/55fc14631c00004800082775.jpeg
my current code is this below
func UploadProfile(w http.ResponseWriter) {
creds := credentials.NewStaticCredentials(aws_access_key_id, aws_secret_access_key,token)
_, err := creds.Get()
if err != nil {
fmt.Printf("bad credentials: %s", err)
}
config := &aws.Config{
Region :aws.String("us-west-1"),
Endpoint :aws.String("s3.amazonaws.com"),
S3ForcePathStyle:aws.Bool(true),
Credentials :creds,
}
svc := s3.New(session.New(), config)
file, err := os.Open("55fc14631c00004800082775.jpeg")
if err != nil {
fmt.Printf("err opening file: %s", err)
}
defer file.Close()
fileInfo, _ := file.Stat()
var size int64 = fileInfo.Size()
buffer := make([]byte, size)
file.Read(buffer)
fileBytes := bytes.NewReader(buffer)
fileType := http.DetectContentType(buffer)
path := "http://img.huffingtonpost.com/asset/,scalefit_950_800_noupscale/" + file.Name()
params := &s3.PutObjectInput{
Bucket: aws.String("MyBucket"),
Key: aws.String(path),
Body: fileBytes,
ContentLength: aws.Int64(size),
ContentType: aws.String(fileType),
}
resp, err := svc.PutObject(params)
if err != nil {
fmt.Printf("bad response: %s", err)
}
fmt.Printf("response %s", awsutil.StringValue(resp))
fmt.Fprintf(w,"done")
}
I do not know why this is not working as my Credentials and buckets are correct . In addition the IMG address works for the image above so do not know why the file is nil
<img height="200" width="200" src="http://img.huffingtonpost.com/asset/,scalefit_950_800_noupscale/55fc14631c00004800082775.jpeg"/>
